The mixer will honor the 150 Clean Pittsburgh Stewards who represent the city’s 90 neighborhoods.

“This event recognizes the work and commitment of ‘Pittsburgh’s finest and cleanest,’” said Boris Weinstein, CPC chair. “The city is fortunate to have this network of people who plan, organize, recruit and lead 20,000 volunteers in twice-a-year spring and fall Redd Ups since 2007.”

Highlight of the mixer will be the presentation of “Bob Awards” for Volunteer of the Year, Neighborhood of the Year, Most Improved Neighborhood and Redd Up Zone Group of the Year. The “Bobbies” are named for the late Mayor Bob O’Connor who put achieving a less-littered city high on his administration’s priorities. His wife, Judy, and son, Councilman Corey O’Connor, will present the awards.

“These deserving recognitions hardly scratch the surface of the thousands of Pittsburghers who buy into the concept that ‘people who care must pick up litter for people who don’t,” said Mr. Weinstein.
